Since its initial launch all the way back in 2017, Fortnite has become one of the most popular video games ever made, averaging over 1 million active players per day. The game's free-to-play Battle Royale mode put it on the map back in the day, but it's the consistent flow of seasonal content that's kept fans coming back year after year, and major expansions that have helped to bring in new players -- expansions like LEGO Fortnite.
